IMPROVEMENT IN HEATING'STOVES.

Specification forming part of Letters Patent No. 128,989, dated July 16,1872 antedated June 22, 187-2.

To all whom it may concern:

Be it known that I, MILTON L. WEBsrER, of the city and county of Albany,State of New York, have invented certain new and useful Improvements inHeaters; and I do hereby declare that the following is a descriptionthereof, reference being had to the accompanying drawing forming a partof this specification, in which 4 Figure 1 represents a perspective viewof the upper part of a heater, embodying the improvements in thisinvention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is avertical view of the same taken at line No.1 in Fig. 2.

The same letters of reference indicate like parts.

My invention relates to that class of stoves denominated heaters; andconsists in the combination of an outer mica light set in the sides ofthe outer jacket, with an inner mica light set in the sides of the innercylinder, in such a manner that the fire within the heater will beexposed to view, and its condition be readily seen.

In the drawing, A represents the base of the heater. B is the sectioncontaining the lire-pot. O is the combustion-chamber, above thefire-pot. D is the usual drum, standing above the combustion chamber. Eis the outer jacket, surrounding the wall E of the combustion-chamber. Fis the outer jacket, surrounding the drum D. The outer jacket E and Fare so arranged that the cold or fresh air can enter the annular spacesa a through the grating or ports a; w, in a direction indicated byarrows, to become heated by the radiation of heat from thecombustion-chamber and the drum, and pass off through any suitableexit-pipe, G, or pipes, to the room or rooms to be heated, all of whichare old and form no part of my invention; but this style of heater hasheretofore had no means provided whereby the fire could be viewed fromthe outside to ascertain its condition, or to admit the passage of lightfrom the combustion-chamber to the outside.

I also fix in the walls of the outer jacket E and opposite to the micasM M, (placed'in the 'walls E of the combustion-chamber,) a second mica,N, or a series of the same, set at a distance from the micas M, so as toleave an airspace between, which mica N will expose the first or innermicas M to view, and will permit the fire to be observed in anunobstructed manner'as readily as if the heater had only the onemica-lighted wall E in the same; the object of my invention being theexposure of the interior of the combustion-chamber and the fire, wherebythe fire will be made to transmit its light through both the wallssurrounding the combustion-chamber, and the jacket surrounding the samein a direct and unobstructed manner.

This invention is simple and comparatively inexpensive, and supplies thedesideratum long desired in this class of heaters.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. The combination of the mica N with the jacket E, when the said jacketsurrounds the wall E of the combustiomchamber 0, provided with the micaM, substantially as and for the purpose set forth.

2. The combination of the outer and inner micas M and N having anair-space between, and located opposite each other, with aheaterconstructed with an inner wall surrounding the combustion-chamber, andan outer jacket surrounding the said mica wall, substantially as and forthe purpose set forth.
